So what does the GZ480 sound like, what distinguishes it?
Between the TRP (GEC KT66) and Supratek preamp’s PSU (Shuguang 6SN7), I’m trying to find the right combination (pair) of rectis to give me the modestly warm engaging sound I like. I had it, but then I improved the isolation of speakers and components and that changed everything. I’ve been working with a GEC U52, 596, Psvane WE274 replica, Mullard GZ32 and KR 5U4G RK Anniversary.. The frustrating thing in this is that the RK notches up the level of transparency, bass and sense of presence far more than the others, so combined with the excellent U52, the sound quality goes into another realm, including some warmth. But the RK is dry, which leaves me feeling disconnected. An example is with blues, with which the right chords, cadence and tone it sings to people, drawing them in emotionally. With the RK and warmish U52, the first two are there, at least nominally, while the tone is something other entirely, almost steely. For me, Romantic era music should sound Romantic (capital R) and blues should sound like blues. Very frustrating situation, one where it would be nice to be able to reach in and tune it a little differently...
So back to the GZ480. What does it have to offer? While my musical tastes range, with the stereo I listen primarily to jazz and classical,
